Be-it known that I, JOHN BARBER, a citizen of the United States,residing at Chi- "cago, in the county of. Cook and State of .Illinois,have invented certain new and useful Improvements in. AntifrictionCenter-Bearings; and I do hereby declare the following to be a full,clear, and exact d'escription of the invention, such as will enableothers skilled r o in the art to which it appertains to make and use thesame.

This invention relates to .antifriction centor-bearings for railway-carsand the like, and has for its object to improve 'the same in the hishereinafter noted.

The myejujtioir consists of the novel de-" i'ices and: combinations ofdevices herein; after described, and defined in the claims.

In the accompanying drawings, which go illustrate the invention, likecharacters 1nd1- ca to like parts throughout-the several views.

Referring-t0 the drawings, Figure '1 is a view, chiefly-in plan, butwith so111e parts broken away, showing the improved center- Fig. 2 showsthe improved center bearing partly in. side elevation and partly inseotion'on the line :0 Q32 of Fig. 1-; and Fig. 3 is a vertical sectiontaken centrally through the roller wearing-plates and retaining ing,

=39 showing the parts separated and showing also a pair of rollers andrivets in full eleva tions v The upper member 1 of the center-bearlng-1S adapted. to be dlrrctly secure d to the body- 5 holster (not shown)of a car, and it is prefere ably in the form of a steel or malleableeast ing.' The lower bearing mcrnberZ of the center bearing is alsoprcferabl in the form of a steel or malleable casting, and it is 40adapted to be directly secured. to a truclo bolster, (not shown) or whenthe center-bean ing is incorporated in a lateral motion ceuter-' hearingsuch as that disclosed in my prioir patent, No. 588,810, issue d of dateZ'L'ugust 24,

Q1897, the said bearing member 2 may con sti'tute the. combined lowerbearin member of the center-bearing proper and he upper bearing memberof the lateral-motion device.

At their central portions the bearing mem- 5p hers I and 2 are formedwith wertically mined hubs or sleeve-portions 3, through which thepivot-bolt (not shown) of the center-bearing is adapted to be passed. inthe usual'way. At its outer portion the lower '55 bearingmember Zisprovided with an upwardly-extended annular flange 4, and ust 1 outwardof this flange 4 the uppe'r'bearing member 1 is provided with adepending annular-,flange'5, which latter flange surrounds the former.The flange 5 serves as a dustguard, and 1t cooperates with the flan e 4to lock the bearing members together 7 resisting lateral thrusts'on saidbearing members.

Conical bearing-rollers 6 are interposed be= tween the twobear1ng-rollers 1 and 2. In

accordance with oneof the principal features of this invention therollers 6 are directly interposed between and engag'with, upper andlower annular wearing-plates 7 and 8,

respectively, which wearing-plates are pref eirably in the form ofpressed steel plates. I

The bodj portions of these wearing-plates 7 and 8 are given conicalform-corresponding to the taper of the conical rollers 6, and theirouter portions are flanged or bent 'respec-' tively downward and'upwardfor engagement with the large outer ends of the said rollers 6. The saidlarge outer ends of the rollers 6, instead of being rounded, are" formedwith straight bevels, as indicated at 6 and the flanged outer portionsof the plates. Tend} are bent to correspond .tothese' bevels 6 The upperWearing-plate 7 loosely rests in a closely-fitting seat formed in thebottom of the upper bearing'member 1, 'and the lower wearing-plate 8loosel-y-rests'in a closelyfitting seat formedin the top ofithe lowerbearing member 2.

' Just outward of their hubs 3 the two bearing members are formed withannularchannels 9, into which the inner edges of the two wearing-plates7 and 8project. Mounted loosely around the hubs 3 of the two bearingplates and projecting into the clearancechannels 9 thereof is a two-partretaining- -.ring 10, the sections of which are, as shown,

telescoped together and rigidly secured together by rivets 11, that passthrough axiallyalin'ed. perforations 12 in the two ring-sections.

moved to admit the raisin the center bearing proper. ring 10, as isevident, holds the wearing-plates 7 and 8 against separation when theparts are removed from the 'eenter-bearin and the sa d wearing-plates,as is also evi ent, maintain the rollers 6 in proper relative positions.It is important when the center-pin is reof the car that the rollers beheld against is laoement. It is also important that the sai rollers bekept together and not be permitted to drop out'of working positions whenthe car is derailed and the upper and lower members of the center -bearing become separated. Railways have hitherto met with considerableexpense on account of the rollers and antifrictionbearings becoming lostunder conditions:

such as above noted. the improved device therefore obvious. Thedetachable wearingplates may such as spring-tempered steel, if desired,regardless of the nature of the metal used to form the bodies of theupper and lower hearing members.

ing plates may be replaced when worn out Without of the center-bearing.Furthermore, the device described is simple, is of comparatively Theimportance of small cost, and is capable 'of being very i quickly andeasily p uttogether andtaken a art. L A

What I. claim is i. In a center-bearing, the combination with upper andlower bearingmembers and T y applied thereto, iii" a retaimngwmg looselyholding Sil-lll wearuigdetachable wearingplntes lates againstseparation, and antll'riotimi caring devices, interposed between saidwearing-plates and held thereby against displacement, substantiallyasdesr-ribed. 2. In a center-bearing, the. combination with'up )er andlower bearing inembers and detacha le wearing-plates applied thereto ofa two-part retaining-ring oosely engaging said two plates and holdingthe some against separation, and conical bearing-rollers interposedbetweensnid wearing-plat es and held I The rat aimingabove described isbe made of hard and tough steel,-

Also these detachable wear- 3 displacement of the body members l 3. In acenter-bearing, the combination,

with upper and lower bearing members and detachable annularwearing-plates applied l thereto, of a two-partretaining-ring loosely lengaging the inner ed es of said annular Wearing-plates and holding thesame against separation, said Wearing-plates having retainin -flanges attheir outer portions, and conioa vbearing-rollers interposed betweeri lsaid Wearing-plates andheld thereby against displacement, substantiallyas described.

4. In a center-bearing, the combination with upper and lower bearingmembers, of annular wearing-plates' detachably' applied thereto andhaving rev'erselyextended annu- 1 lar sto -flanges at their outerportions, and 1 conica bearing-rollersi interposed between and'lowerbearing members, substantially as said annular wearingplates with theirouter ends arranged, to thrust against the sto flanges of saidwearing-plates,substantial y as described.

5. In a center-bearing, the combination 1' with upper and lower bearingmembers 1 and .2 respectively, provided with alined hubs 3 andclearance-channels "9., the said lower member 2 having the annularflange 4, and said boa-ring member l 'having the annular E flange 5surrounding s'aichflange 4, or the ah- E nular wearing-plates. 7 alhd 8fitting sests formed respectively in the said members 1 enld 2, thebearing-rollers 6 interposed be: tween said wearing-plates, and thetwo-part retaining-ring 10 working Within the clearance-channels 9 andengaging the inner edges of said annular wearing-plates 7 andS and iholding the same against separation, sub

' stantially as described.

v In testimony whereof I affix my in presence of two witnesses.
